Title: Automatic focus controller
Inventor: KONISHI KAZUKI
IPC: G02B7/28
Filed: 1987-06-24
Abstract: PURPOSE: To improve the possibility of focusing to a distance measuring object by employing no information about distance measuring information which do not lie within a fixed range based on range finding information of midpoint.  
     CONSTITUTION: Three distance measuring results on a screen which are sent from a distance measuring circuit 7 through an interface circuit 8 are read out, thereby obtaining the closest point LN, the midpoint LM and the farthest point LF. The midpoint LM being a reference is compared with the closest point LN. If the difference between them is larger than a fixed value (k) which is determined by the focal distance of a lens, an opening value F and the number of distance measuring points, the midpoint LM alone is considered and effective distance measuring result at this stage, ignoring the closest point LN. The midpoint LM is compared with the farthest point LF. If the difference between them is larger than the value (k), the midpoint alone is considered an effective distance measuring result, ignoring the farthest point LF, and a focus control signal in response to the midpoint LM is generated. Thus the possibility of focusing to the distance measuring object can be improved.
